Wie rechne ich... Brechung und Dispersion am Prisma?

Erste Brechung

beta_1 = asind(sind(alpha_1) * n_L / n_b)
beta_1 = 25.3755

Zweiter Einfallswinkel

epsi = 180 - gamma
epsi = 120
beta_2 = 180 - epsi - beta_1
beta_2 = 34.6245

Zweite Brechung

alpha_2 = asind(sind(beta_2) * n_b / n_L)
alpha_2 = 69.6394

Ablenkung

delta_1 = alpha_1 + alpha_2 - gamma
delta_1 = 54.6394

Zweiter Winkel mit Gesamtormel

delta_2 = alpha_1 + asind(sind(gamma - asind(sind(alpha_1) * n_L/n_r)) * n_r/n_L) - gamma
delta_2 = 49.0366
deltaDelta = delta_1 - delta_2
deltaDelta = 5.6029
